Re: Infinity PS-12 Powered Subwoofer Fired Amplifier
Yes, the power supply is an issue. The newer PS210 is rated 150w RMS, 210w "Average RMS", 300w "Marketing RMS" and 500w Peak dynamic, very generous ratings indeed with the same power supply as the PS-10/PS-12. PS210 have 2SK3594 MOSFETs instead of IRF640.
Attaching an external Class D Amp with this PS-12's power supply is just the last resort.
I also have a Behringer A500 Class A/B sitting around doing nothing... might be worth a try to see if the amp is a limiting factor to my dual subs reaching only 37Hz -3dB... It does do 25Hz -10dB with Audyssey.
